摘　　要：Traditional space group determination methods are all in reciprocal space,which involves ambiguous identification on some space groups which have glide plane and screw axes.The novel strategy herein for space group determination in real space is based on the atom resolution high angle annular dark field(HAADF)technology.Three HAADF images in three specific crystal zone axes are needed at most.The proposed strategy for space group determination is easy and effective.
